How do I determine the correct capacity boat trailer for my boat?

Choosing the right boat trailer capacity requires knowing both the dimensions of your boat and its total loaded weight.

1.Measure your boat length and beam

• • Measure the length of your boat horizontally from the bow eye to the drain plug (not the overall length including motors or bow pulpit).
  • Find the beam (the widest point of the boat). These measurements determine the trailer’s frame length and width requirements.
  • To make this easier, download and fill out our Boat Measurement Forms.

2. Calculate your boat’s total weight

Start with the boat’s dry hull weight, then add:

• Outboard motor(s) weight
• Fuel capacity (multiply gallons × 6.1 lbs per gallon)
• Water capacity (multiply gallons × 8.3 lbs per gallon)
• Batteries
• T-top or hard top (if equipped)

Add all of these together, then multiply the total by 1.1 to account for 10% additional gear weight (coolers, food, tackle, electronics, etc.).

Example:

• Dry hull: 2,800 lbs
• Motor: 400 lbs
• Fuel: 50 gallons × 6.1 = 305 lbs
• Water: 10 gallons × 8.3 = 83 lbs
• Batteries & T-top: 200 lbs
• Subtotal = 3,788 lbs
• Gear allowance (10%) = 379 lbs
• Total trailer capacity needed = 4,167 lbs

3. Choose the next heavier trailer model
Always select a trailer rated for slightly more than your calculated weight. This provides a margin of safety and prevents overloading.

To make the process even easier, use our Boat Weight Calculator Tool. Then, bring your completed boat measurement forms and calculator results to your nearest dealer. You can use our Find a Dealer Tool to locate a certified Venture dealer near you.
